  • The finish and color options are limited to the configurations listed in the product data, so it may not match every build aesthetic.
  • Compatibility is described for mil-spec AR lowers and standard components, so non-standard setups may require additional verification.
  • The product details note .250" pivot and takedown pins, which means builds using different pin sizing are not covered by the provided specifications.
